Yeah, I agree -- the current semantics aren't very useful anymore. I'd actually like to just redefine the FAKE_RDMA flag's meaning. Some of the BTLs assume that there will be one set of prepare_src / prepare_dst calls for each put/get call. This won't work for one-sided RDMA, were we'll call prepare_dst at window creation time and reuse it. I'd like to have FAKE_RDMA set for those BTLs. Brian
